Public bug reported:
Binary package hint: linux-source-2.6.20
The USB devices (mouse, printer) connected to my Toshiba Satellite M-40
laptop running on Gutsy started to randomly stop working today. I've had
Gutsy installed for just over a month now, and had been running Feisty
for 6 months with no problems with either device -- no idea what caused
this to stop working, although I did install several updates for Gutsy
today. Rebooting usually brings back functionality for a bit, but the
devices will eventually get dropped -- it has happened as soon as typing
the user name in GDM, but often while typing something in the actual
Gnome session, e.g. into internet browser search fields, terminal, or
OpenOffice.
I noticed this first with the mouse -- it is a Microsoft Standard
Wireless Optical Mouse. Unplugging and then plugging back in does *not*
help, even to a different port. The printer, a Samsung ML-1740 laser,
also gets dropped. I managed to grab the outputs from lsusb before and
after the failure, as well as dmesg and Xorg.0.log, will attach.
Again, I have had *no* USB problems with Ubuntu for seven months, and I
have no idea what could have happened to trigger this. My keyboard and
touchpad still work after USB devices stop working, so I am able to
continue using the laptop.
The last few lines from dmesg could be helpful:
[ 232.188000] uhci_hcd 0000:00:1d.0: host controller process error, something
bad happened!
[ 232.188000] uhci_hcd 0000:00:1d.0: host controller halted, very bad!
[ 232.188000] uhci_hcd 0000:00:1d.0: HC died; cleaning up
[ 232.188000] usb 1-1: USB disconnect, address 4
[ 232.192000] drivers/usb/class/usblp.c: usblp0: removed
[ 232.192000] usb 1-2: USB disconnect, address 5
